COMBINED RECIPROGATING- AND TURBINE ENGINE INSTALLATION.

To all whom it may concern:

Be it known that I, JOHN IRVING, a subject of the King of Great Britainand Ireland, and a resident of Gardross, in the county of Dumbarton,Scotland, have invented certain new and useful Improvements inConnection with Combined Reciprocating and Turbine Engine Installations,and of which the following is the specification.

In combined reciprocating-and-turbine-engine installations for generalor marine purposes, the turbine engine is arranged between tworeciprocating engines having separate condensers into which the turbineengine exhausts through separate exhaust pipes on each side. In sucharrangements, should a defect arise in one of the condensers or in itsair or circulating pump or other connection, the three propellingengines have to be stopped to enable the repair to be effected. Thisresults in great loss of time, and at sea may involve the ship inserious difiiculty.

This invention has for its object to overcome these disabilities andrender it possible to repair a condenser or its air or circulating pumpor other connection without its being necessary to stop any of the threepropelling engines.

In carrying out the invention, a closure device consisting of a stopvalve is arranged in each of the exhaust pipes or passages between theturbine engine and the condensers, and should a condenser or its air orcirculating pump or other connection on one side require repair, thestop valve in the exhaust pipe connected with that condenser is closed,thereby shutting off connection between the turbine engine and thedefective condenser, so that the necessary repair can then be effectedconveniently, the propelling engines, of course, then exhaustingentirely into the other condenser.

In order that the invention and the manner of performing the same may beproperly understood there are hereunto appended two sheets of drawingsthroughout which like reference symbols indicate like parts, and inwhich- Figure 1 (Sheet l) is a plan showing diagrammatically thecombined reciprocatingand turbine-engine installation, while Fig. 2(Sheet 2) is a sectional end elevation drawn to a larger scale, andshowing an example of the means provided, according to this invention,for shutting off connection between the turbine engine and thecondensers.

Specification of Letters Patent.

Application filed October 12, 1909.

Patented Apr. 26, 1910.

Serial No. 522,245.

As shown in the drawings a turbine en gine A is arranged between tworeciprocating engines A A having separate condensers B B into which theturbine engine A exhausts through separate exhaust pipes C C The steampasses from the reciprocating engines A A to the turbine engine A by theusual branch pipes D D and there are also provided the usual branchconnections E E leading from the reciprocating engines direct to thecondensers, these branches being fitted with valves G G as usual, sothat the turbine may be cut out altogether when the reciprocatingengines A A are going astern, for example.

In carrying out the invention, a closure device consisting of a stopvalve C (Fig. 2) is arranged in each of the exhaust pipes or passages CC between the turbine engines A and the condensers B B andshould acondenser or its air or circulating pump or other connection on one siderequire repair, the stop valve G in the exhaust pipe connected with thatcondenser is closed, thereby shutting off connection between the turbineengine A and the defective con denser, so that the necessary repair canthen be eifectedconveniently, the exhaust steam, of course then passingentirely into the other eon enser.

The stop valves G employed are, as shown, preferably of'the clack valvetype. They are arranged to work across the pipes C C and are centrallyattached, each to a vertical spindle D connected at the outside to anysuitable mechanism (not shown) for opening and closing the valve. Anyother suitable type of stop valve, however, may be employed.

What I claim is In a valve mechanism for the purpose described, a clackvalve arranged in the passage controlled, a bracket thereon and a pincarried thereby, in combination with an operating stem for said valveprovided with a slotted end engaging said pin. and a stuffing boxthrough which said stem extends, substantially as described.

In testimony whereof I have signed my name to this specification, in thepresence of two subscribing witnesses.

JOHN IRVING.
